New evidence suggests that teenage boys who receive sex education are three times more likely to use condoms when they lose their virginity. And that's not the only good news: The same study, conducted by the Centers for Disease Control in Atlanta, showed that all teens who receive some kind of sex education will delay sex until at least age fifteen. The CDC did not differentiate what kid of sex education was taught — it treated abstinence-focused education the same way it studied more progressive forms of sex ed — though research released earlier this year showed that abstinence only programs don't really work. (Interestingly, the only form of sex ed required in Jamie Lynn Spears' home state of Louisiana is abstinence only; Jessica Sierra's home state of Florida also requires abstinence only education but does not impose either sex ed or contraceptive practices on its students.)
